The interest rate play a key role in your financial life. Whether for a real estate loan, a consumer loan or even your savings products, they determine the cost of borrowing or the gains you can make from your investments. Understanding how interest rates work and their impact on your finances is essential to making informed decisions and optimizing your financial management. This guide explains everything you need to know about interest rates and how they influence your borrowing, saving and investment.
1. What is an interest rate?
One interest rate is the cost you pay to borrow money or the return you earn on an investment. It is expressed as a percentage of the amount borrowed or invested and is calculated on an annual basis, although it can be applied monthly or quarterly.
A. The different types of interest rates
There are several types of interest rates, depending on the circumstances and financial products to which they apply:
- Fixed interest rate : This rate remains constant throughout the duration of the loan or investment, which means that you always pay or earn the same percentage.
- Variable interest rate : This rate fluctuates according to different economic factors, such as inflation or central bank decisions. Variable-rate loans can lead to higher costs if rates increase.
- Nominal rate : This is the rate on the loan or savings contract. It does not include inflation or additional costs.
- Real rate : It takes into account inflation and represents the real return or cost of your loan or investment.
2. How interest rates influence your borrowings
When borrowing money, interest rates play a crucial role in the total cost of your loan. The higher the interest rate, the more interest you pay over the term of the loan.
A. The impact of interest rates on a real estate loan
In the context of Real estate loaninterest rates are often a decisive factor for the total cost of the asset. A lower interest rate can save you thousands of euros over the duration of your loan.
Example : If you borrow 200,000€ over 20 years with an interest rate of 2%, you will pay about 44,000€ interest. If the rate rises to 3%, total interest increases to approximately 66,000€a difference of 22 000€.
B. Fixed rate vs variable rate for borrowings
When you contract a loan, you often have a choice between a fixed rate and one variable rate.
- Fixed rate : You pay the same interest rate throughout the duration of the loan, allowing you to predict your payments and protect yourself against rate increases.
- Variable rate : This rate may fluctuate depending on market conditions. Although it is often lower at the start, it can increase, making your monthly payments higher.
C. The effect of interest rates on consumer credit
The consumer credit (personal loans, revolving loans) are generally accompanied by higher interest rates than real estate loans. A high interest rate can quickly increase the total cost of credit, especially if you take credit over a long period.
Example : A consumer loan of 10,000€ at a rate of 6% over 5 years will cost you about 1,600€ interest. If the rate increases to 10%, you will pay about 2,700€ interest.
3. The impact of interest rates on your savings
Interest rates influence not only your borrowing, but also your investments and your savings products. The higher the interest rates, the more money you earn on your savings accounts, books or bonds.
A. Interest rates on savings books
The Savings booklets as the Book A or Sustainable and Solidary Development Booklet (LDDS) offer a return based on interest rates set by the authorities. Although these booklets are secure, their interest rates are often low, especially in low-rate periods.
Example : If you place 10,000€ on a Booklet A with a rate of 1%, you will win 100€ interest in one year. If the rate increases to 2%, you will win 200€ over the same period.
B. Bonds and interest rates
The obligations are debt securities issued by governments or companies, which pay you regular interest. Interest rates directly influence bond yields. In times of rising interest rates, bonds already issued at low rates may lose value.
C. The role of compound interests
The compound interest are one of the most powerful tools to make your savings grow. When the interests you earn are reinvested, they themselves begin to generate interest, creating a snowball effect.
Example : If you invest 10,000€ at an interest rate of 5% for 10 years, you will win 6,288€ interest with compound interest, compared to only 5,000€ with simple interests.
4. How interest rates affect your investments
The interest rate financial markets and can have a significant impact on your Investment.
A. Impact of rates on shares
Shares can be affected by interest rates, especially in times of upswing. Indeed, as interest rates increase, companies can see the cost of borrowing increase, which can reduce their profits and market value.
B. Investing in real estate based on interest rates
When interest rates are low, it is often more advantageous to borrow to buy real estate. This can increase demand for real estate and raise prices. Conversely, as rates rise, borrowing costs increase, which can slow down purchases and lower real estate prices.
C. Bonds and interest rates
When interest rates rise, the obligations lower rates are becoming less attractive, which may lower their value in the secondary market. Conversely, when rates fall, bonds already issued at higher rates gain value.
5. How to take advantage of changes in interest rates?
Variations in interest rates can be an opportunity if you know how to take advantage of them.
A. Refinance your loans
If interest rates decline after taking out a real estate loan or other type of credit, it may be advantageous to renegotiate your loan to get a lower rate. This can reduce your monthly payments or shorten the repayment period.
Example : If you have a 3 % real estate loan and the rates rise to 2 %, renegotiating your loan can save you thousands of euros over the duration of the loan.
B. Enjoy rate increases for your savings
In times of rising interest rates, you can seek to place your liquidity on accounts or bonds with higher returns. Investments such as obligations or discount booklets become more attractive.
